Should i even take the time to learn Qt?

Okay so I installed Qt and have been working around with it a little, following some dude on youtube :D. But I can't help to notice that when creating the UI's, you have to drag and drop the "Button" to where you want it to be... (Using the Qt Creator) Unlike in GLUT where you accually have to program everything. Is Qt just teaching me how to be lazy? Or should i accually be learning Qt?

Don't know Creator. Designer is older GUI tool to define UI. Design is stored as xml-format. That can be compiled into code or even parsed runtime. Perhaps lazy, but it decouples looks from functionality. That is nice.
